Specification of Letters Patent.

Patented Sept. 26,1916.

Application filed January 26, 1910. Serial No. 540,163.

To all whom it may concern:

Be it known that I, HERMANN Fo'rTINo-ER, a subject of the King ofBavaria, and a resident of Stettin, Germany, have invented a new andImproved Transmission Device,

of which the following is a full, clear, andexact description.

This invention relates to certain improvements in hydraulic powertransmitters of that type in which a centrifugal pump impeller and aturbine rotor constitute the driving and driven members and are suitablyjuxtaposed whereby the liquid thrown out by the impeller by centrifugalforce may impinge upon and produce the desired rotation of the drivenmember, both by the fluid velocity energy and the fluid pressure energy.The kinetic energy of the liquid is absorbed in the driven member andsaid liquid is then guided back to the inlet of the propeller. In suchhydraulic power'transmitters, the driving and driven members arepreferably arranged coaxially and the space between the driving anddriven members is made as short as possible to utilize to the fullestextent the kinetic energy of the liquid traveling at high velocity.

In my prior and co-pending application Serial No. 322,395, filed June19, 1906, I have disclosed a considerable number of different formswhich I have devised, by means of which the desired results may besecured. In certain of these forms, the driving and driven membersdefine the entire circuit for the liquid While in other forms non-rota-,

table, annular, liquid guiding membersare interposed in the circuiteither to return the liquid from the driven member to the driving memberor to guide the liquid from the driving to the driven member. I havealso disclosed different constructions in .some of which the guidingmember is stationary, and in others it is adjustable either bodily or bythe individual adjustment of the separate vanes, toregulate or controlthe flow and if desired, to reverse the direction of rotation of thedrivenmember. In said application, I have claimed my invention broadlyand have claimed specifically the particular type in which the drivingand driven members make up the entire circuit.

In my co-pending' a plication Serial No. 540,162 filed on evendateherewith, I have v dividedvout from said application Serial No.

322,395, and have claimed specifically, those forms in which anon-rotatable annular guiding member is interposed in the circuit buthave not claimed specifically those forms in which a regulation orcontrolling of the liquid is secured by an adjustable member. 1

In the present application, I have claimed broadly the adjustable meansfor regulating, varying or controlling at will, the flow of the fluidand have more specifically claimed a construction in which the guidingmember is longitudinally movable. The preferred embodiment of theinvention herein claimed is a form in which the guide member conductsthe liquid in the plane of rotation of said members from theperipherally disposed outlets of the driving member to theconcentrically arranged inlets of the driven member. The specific formin which a stationary or movable guiding member encircles both thedriving and driven member and conducts the liquid from the peripherallydisposed outlets of the driving member to the peripherally disposedinlets of the coaxial driven member, is claimed more specifically in myco-pending application Serial No. 842,409 filed June 2, 1914.

In carrying out my invention, the driving, driven and guiding membersare preferably inclosed within a casing containing a constant volume ofliquid, and preferably the casing is of such shape as to closely followthe contour of the members and thus confine substantially all of theliquid within the members themselves. The liquid is caused to move in adirection having a radial component, by the driving member and, as itleaves the outlets, it tends to flow in a tangential direction due tocentrifugal force. The guiding member receives this liquid .and directsits flow to the driven member and by varying or adjusting this guidingmember or the vanes thereof, I am able to control the direction of flowand the angle ofimpaot of the liquid against the vanes of the drivenmember. Thus, I may vary the torque and the relative s eed ratio of thedriving and driven mem ers. I may not only control the direction of flowof the liquid, but may control the amount of the flow as for instanceby. permitting the guiding member to partially shut ofl' or close theoutlets from the driving member.

Reference is to behad to the accompanying drawings forming a part ofthis specification, in which Figure 1 is an end view in elevation, of

The energized operative fluid is shot fromthe primary turbine wheel 2 into any one of a plurality of preliminarystage rings 3 and 4 on a guide wheel 5.

In the position of the guide wheel 5 illustrated in Fig. 2 the operativemedium will first pass into the preliminary stage 3, but

in the position shown in Fig. 3, the operative medium will first passinto the preliminary stage 4 on the guide wheel 5. F romthe preliminarystages on the guide wheel 5, the operative medium passes to any one of aplurality of passage rings 6 and 7, on the first stage of a secondaryturbine wheel 8, which is securedin any well known manner to a secondaryshaft 9, according to the position of the guide wheel 5. In its firststage on the secondary turbine wheel 8, the velocity energy of theoperative medium is absorbed, .and the operative medium directed in theproper direction to any one of a plurality of second-stage passage rings10 and 11 on the guide wheel 5.

From the second-stage guide passage on the guide wheel 5, the operativemedium passes to a second stage 12 on the secondary turbine wheel 8,from whence it returns to the intake side of the primary turbine wheel2. The number of stages on the guide wheel 5 and the secondary turbinewheel 8 may be varied according to the conditions desired. The number ofpassage rings on the stages of the guide wheel 5 and the secondaryturbine wheel 8 may be also varied, in order to obtain a variety ofspeeds or a gradual reversal of the secondary turbine wheel 8 fromrotation in one direction to rotation in the opposite direction.

In the form illustrated in Figs. 1 to 4, the

guide vanes in the passage rings 3, 6 and 10 are curved in the oppositedirection, re-

spectivel to the guide vanes in the passage rings 4, i and 11, so thatthe operative-medium will be diverted in different directions, accordingto the circuit in which it travels, thus rotating the secondary wheel indifferent directions, according to the circuit in which it travels.These vanes may be so curved as to give different speeds to thesecondary wheel 8, instead of different directions.

In order to bring any of the passages in the guide wheel 5 intooperation, the guide wheel 5 is shifted bodily by means of a pluralityof screws 13, which are secured in any well known manner to the wheel 5,and extend out through packing boxes 14. Each of these screws 13 areengaged by nuts 15, which are rotatably supported on a frame 16, whichis secured in any well knownmannor on a casing 17, which incloses theactive members of the turbine transmission. Each III of the nuts 15 isprovided with teeth on its outer periphery, forming a pinion, whichmeshes with a central gear 18 rotatably secured in any well known manneron the shaft, 1. Various difi'erent means may be provided for rotatingthe gear 18, such as handles 19. By rotating the gear 18, the pinionnuts 15 are correspondin ly rotated 1n the opposite direction, there yadvancing or withdrawing the screws 13 bodily, thus reciprocating evenlythe guide wheel 5. While the handles 19 are shown for operating the gear18, distant or automatic control may be used. The casing 17 is providedwith stufiing boxes 20 and 21, which surround the shafts 1 and 9 wherethey enter the casing.

The casing is entirely filled with liquid which is prevented fromescapin by the stufling boxes surrounding the sha ts and is continuouslycirculated through the driving, driven, and guiding members. It is ofcourse evident that such portion of the liquid as occupies the spaceoutside-of these members does not aid in the transmission of.

power but prevents the escape of liquid from between said members andavoids the necessity of stufiing boxes or a tight fit at those placeswhere liquid passes from one member to the other. The guiding memberserves not only to control the direction in which the liquid istraveling when it impinges on the blades of the driven member, but, ifstopped in an intermediate position, serves to control the amount ofliquid flowing from the driving to the driven member.

In the formillustrated in Figs. 5 to 8, there is shown a single-stageguide Wheel, designated by the number 22, with a plurality of passagerings 23 and 24. The means for shifting the guide wheel also is somewhatdifierent from that illustrated in Figs. 1 to 3, and consists of aplurality of bell crank levers 25, pivotally secured in any well knownmanner to a casing 26, inclosing the operative parts of the turbinetransmission. These bell crank levers 25 have a slidingly pivotedengagement with lugs 27 secured at intervals on the guide wheel 22. Theouter arms of the bell crank levers 25 are connected by means of links28 to a collar 29, which is splined onto a sleeve 30, which in turn issupported on a primary shaft 31 in such a manner as to permit said shaftto rotate without rotating the sleeve. The collar 29 may be shifted backand forth on the sleeve 30, thereby reciprocating the guide wheel 22,bringing either of the passages 23 and 24 into operation.

The primary shaft 31 is provided with a primary turbine 32, which issecured to it in any well known manner. The primary turbine 32 isadapted to impart energy to an operative fluid, which will pass througheither one of the passages 23 or 24, accord ing to the position of theguide wheel 22, into a passage ring 33 on a secondary turbine wheel 34,which is secured in any well known manner to a secondary shaft 35. Thecurvatures of the blades in the passage rings 23 and 24 are illustratedin the right and left-hand sides, respectively, of Fig. 8. The forms ofthe blades on the primary turbine wheel 32, and the secondary turbinewheel 34 are also illustrated in Fig. 8.

Figs. 9 and 10 illustrate another form of a shiftable guide wheel 36,having a'plurality of passage rings 37 and 38, which are adapted to bebrought into coaction with a primary turbine wheel 39 on a primary shaft40. In this form, a secondary turbine wheel 41 is provided on asecondary shaft 42, of such a form that when the passage ring 37 isbrought into coaction with the primary turbine 39, the operative mediumwill be delivered to .a longer circuit 43 on the secondary wheel 41. If,however, the passage ring 38 is shifted into coaction with the primaryturbine wheel 39, as illustrated in Fig. 9, the operative medium will bedelivered to a shorter circuit 44 on the secondary turbine wheel 41. Theblades in the passages 37 and 38 on the guide wheel 36, and in thecircuits 43 and 44 on the secondary turbine 41, may be conformed eitherto give diiferent directions of rotation to the secondary shaft 42, ordi-iferent speeds of rotation.

The form illustrated in Figs. 11 to 13 is similar to the formillustrated in Figs. 1. to 4, to the extent that it has a primaryturbine wheel 45 on a rimary shaft 46, and a secondary shaft 4%, whichhas thereon a secondary turbine wheel 48, divided into two stages 49 and50. There is also provided a guide wheel 51, which, however, difi'ersfrom the guide wheel shown in Figs. 1 to 4, in that it hasmultiple-stage passage rings 52 and 53, which coact with the stage 49 onthe secondary turbine wheel, and a single-stage passage ring 54, whichdoes not coact with an intermediate stage on the secondary turbinewheel, but guides the operative fluid direct from the primary turbinewheel 45 to the second stage 50 on the secondary turbine wheel 48.

The curvatures of the vanes or blades in the passage ring 54 areillustrated in the upper half of Fig. 13, and the curvatures of thepassage rings 49, 52 and 53 are illustrated in the lower half of Fig.13. These passage rings will give opposite directions of rotation to thesecondary turbine Wheel 48, as illustrated in Fig. 13. In these Figs.11, 12 and 13, another form of shift for a guide wheel is illustrated.This consists of a plurality of rods 55, which are secured in any wellknown manner to the ring 54 at one end, and to pistons 56 at the otherend. These pistons are adapted to reciprocate in cylinders 57, securedin any well known manner to a casing 58, which incloses the active partsof the turbine transmission. The pistons 56 may be operated by anymotive fluid, such as compressed air, steam or the like, which issupplied through pipes 59 and 60.

Figs. 14, 15 and 16 illustrate various forms in which, instead ofshifting the guide wheel bodily, the vanes on the guide wheel aremanipulated to be curved or deflected in difierent directions, so as tovary the flow of the operative medium from the primary turbine wheel tothe secondary turbine wheel, in order to produce various speeds anddirections of rotation in the secondary turbine wheel.

In Fig. 14, 61 illustrates a primary shaft, on which is secured aprimary turbine 62, which energizes the operative medium and directs itinto a guide wheel 63, which is provided with movable blades or vanes64:, secured'in any Well known manner on pivotal shafts 65. The shafts65 may be operated simultaneously or in groups to obtain any desireddirection or. curvature of theblades 64, by means of cranks 66. Theoperative fluid passes from the guide wheel 63 to a secondary Wheel 67secured on a secondary shaft 68.

In the form illustrated in Fig. 15, 69 represents a primary shaft, onwhich is secured a primary turbine 70, which energizes the operativefluid and directs it to a first stage 71 on a secondary turbine wheel 72on a secondary shaft 78. The operative fluid passes from the first stage71 into a guide Wheel 73 formed on part of an inclosing casin 74:.Movable vanes 75 are provided in tlns guide wheel 73, and are adapted tobe manipulated by means of a plurality of cranks 76, one of which onlyis shown. The operative fluid passes from the guide wheel 73 into a.second stage 77 on the secondary turbine wheel 72, from whence it is Idelivered back into the intake side of the primary turbine 7 0. Theblades 75 in this form may be made flexible if desired.

Fig. 16 diflers from Fig. 15 merely in the form of the shiftable guideblade, and the parts are designated by the same numerals.

Fig. 17 illustrates diagrammatically one form of guide wheel withshiftable guide blades. The guide blades in this form comprisestationary portions 79 and movable portions 80. The movable portions 80are adapted to be shifted from the position shown in the upper half ofthe figure to the position show in the lower half of the figure, so asto change the direction of rotation transmitted from a primary turbine81 to a secondary turbine 82.

Fig. 18 illustrates diagrammatically a form in which both portions 83and 84 of shiftable guide vanes on the guide wheel are movable to coactwith stationary guide vanes 85 on the guide wheel, to form variouspassages, through which the operative fluid will be directed from theprimary turbine wheel to the secondary turbine wheel. In this figure,the movable portions 84 of the guide vanes are illustrated as beingflexible.

Fig. 19 illustrates diagrammatically the ideal form, based on the formillustrated in Fig. 18, in which movable guide blades 86 are flexiblethroughout their length, so as to form perfectly. curved vanes to coactwith stationary guide vanes 87.

In Figs. 18 and 19, I have not illustrated in detail the means formoving the vanes or blades, as such means, per 86, forms no part of mypresent invention. Any suitable means may be employed for accomplishingthe result andin these figures I merely desire to indicate the positionsto which the vanes or blades may be moved, rather than attempting todisclose any particular means for so moving them.

While I have shown various structural forms as illustrating variousforms of my invention, I do not wish to be limited to any of theseforms, but desire to cover the invention of transmitting power from oneshaft to another shaft by fluid pressure means, comprising a primaryturbine wheel and a secondary turblne wheel, with the mterposition ofshiftable guide means, to take up the reaction of the operative fluid,and to properly direct the operative flnidfrom the rimary turbine wheelto the secondary turbine wheel, so as to obtain various speeds anddifferent directions of rotation.
